Question

)A set of equations is given below:

Equation A: y = x + 1
Equation B: y = 4x + 5

Which of the following steps can be used to find the solution to the set of equations?

x + 1 = 4x + 5
x = 4x + 5
x + 1 = 4x
x + 5 = 4x + 1

Answer 1

x + 1 = 4x + 5

Explanation:

Simultaneous equations to solve x so equate the equations together.

Answer: x + 1 = 4x + 5 (first option)
